Problems solved by technology

[0002] At present, the flushing devices used in public toilets generally complete the flushing process regularly and quantitatively. Most of them sense the user's presence through some infrared sensors, and then after the user leaves for a period of time, the flushing process is completed regularly and quantitatively according to the set value. For flushing, you can’t choose different flushing time and flushing volume according to whether the user is defecating or urinating. To a certain extent, it wastes water resources, and it is easy to form scale-like attachments after long-term use, which is difficult to clean

Abstract

The invention discloses a toilet flushing device for intelligently recognizing urine and excrement. The toilet flushing device comprises an infrared sensor, a weighing sensor device, a controller, a power module, a water flushing device, a toilet detergent adding device and a squat toilet set. The infrared sensor, the weighing sensor device and an electromagnetic valve are connected with the inputend of the controller. The output end of the controller is connected with the water flushing device and the electromagnetic valve. The toilet detergent adding device comprises a toilet detergent tankfor storing a toilet detergent and the electromagnetic valve. The toilet detergent adding device is connected with a flushing water inlet pipe of the squat toilet set. The electromagnetic valve is installed at a toilet detergent outlet of the toilet detergent tank and controlled to be turned on/off by the controller. The power device supplies power to the whole system. Urine and excrement can beintelligent distinguished and different flushing time and flushing volumes can be selected, water resources are saved, and the squat toilet set can be kept clean.

Description

Technical field [0001] The invention relates to a toilet flushing device, in particular to a toilet flushing device with a special structure. The device has the function of automatically distinguishing urine and feces, and selects different flushing volumes and flushing times according to different situations, belonging to the toilet appliance device. Background technique [0002] At present, the flushing devices used in public toilets generally complete the flushing process regularly and quantitatively. Most of them use some infrared sensors to sense the presence of the user, and then after the user has been away for a period of time, it will complete the flushing process regularly and quantitatively according to the set value. For flushing, it is not possible to choose different flushing time and flushing volume according to whether the user is defecate or urinate, which causes a waste of water resources to a certain extent, and it is easy to form attachments similar to scale af...
